able others skilled in the art to which it a ppertains to make and use the same.

The present invention relates to a devlce for automatically coupling and uncoupling railway carriages provided with the usual screw coupling.

Vith this device, which enables the coupling and uncoupling to be effected even when the screw coupling is screwed up, the force of the colliding buffers of the carriages is utilized for the coupling operation.

In the accompanying drawings, Figure 1, is a top view of the device on a carriage in its position to prepare the coupling parts, not shown, for coupling. Fig. 2, is a side view partly in section, with the coupling parts ready for coupling. Fig. 3, is a side view partly in section at the moment of the collision of the buffers and the pushing back of the lifting mechanism. Fig. 4, is a detail which shows the adjustment of parts for releasing the lowering mechanism of the coupling which is necessary in uncoupling carriages, coupled by means of a screw coupling. Fig. 5, is a top view of the screw coupling. Fig. 6, is a side view of the coupling with somewhat modified lifting mechanism, and Fig. 7, is a section of the coupling on line 77 of Fig. 6.

The device for automatically coupling or uncoupling the carriages comprises two main parts, these are the device for lifting the coupling and the device for lowering the same at the moment of collision of the buffers, which causes the carriages to be automatically coupled.

The device for lifting the coupling is arranged underneath the carriage and comprises a toothed pinion 11, keyed to a shaft 10, which moves under the pressure of a spring 12, in the direction of the arrow, and coming into engagement with the guiderack 13, guided by rollers 14 which are supported in hangers 15, moves said rack 13. The upper side of the rack 13 is provided with notches 16, to engage a pawl 17 fastened to the shaft 18. This pawl'17 is pressed downward by a spring 19, so that when in engagement with one of the notches 16, it locks the rack. If the pawl is released out of engagement, by turning its shaft 1", by means of a spanner applied to its angular end 18 (Fig. 1) of the same, the rack, under pressure of the tense spring 12 which swings the toothed sector 11 to the left, slides automatically from under the carriage into its farthest left hand position, (Fig. 2).

The front, bent up end of rack 13 is provided with two rollers 20, which during the forward movement of the rack come in contact with a guide member 21, which is fastened to the rear nut 22 of the usual screw coupling. This nut 22 and the nut 24 are kept from accidental rotation, by a two part guide bar 23, one part of which bears on the nut 22, while the other part bears on the front nut 24, of the screw cou pling, Both parts of the guide bar are held in position by spring clips 25, secured to the nuts. On account of the reciprocal movement of the rollers 20 and of the guide member 21 the screw coupling is raised when the rack 13 is pushed outward and takes up the position shown in Fig. 2, and the front coupling eye 26, of the screw coupling is prevented from falling downward by a cross-bar 27, secured to the pins of the front nut.

Figs. 6 and 7 show a modification of the lifting mechanism consisting of a bar provided with rollers 20 fastened to the rear nut 22, and a guide member 21 secured on the rack 13.

For automatically lowering the screwcoupling the force of the collision of two colliding carriages, is utilized by means of the butters. The mechanism for this purpose comprises the parts described as follows: On the shaft 10, carrying the toothed sector 11, two block-sheaves 28 are fastened syi'nmetrically to the longitudinal axis of the carriage. Around each of these sheaves is coiled achain, fastened, one end to the sheaves 28 and at the other end to shaft 30, which latter is rotatably mounted in oriflees in the bent ends of the bars 31. The bars 31 are slidable in guides 32in the rear of the buffers. hen it is desired to efiect This releases the sliding rack 13 and the said rack is forced forward by the rotation of the pinion 11 which moves under the tension of the spring 12. At the forward movement of the rack 13, the rollers 20, engage the guide members 21 of the screw coupling and raise the same to the position shown in Fig. 2, thereby uncoupling the cars.

hen it is desired to move cars having our coupling device, without engaging the couplers as in switching or shunting operations, the bar 31 is forced transversely against the resistance of the spring -38 in order to disengage the pawl 37 from the bar 31. Vith the pawl 37 disengaged from the bar 31, an inward movement of. the

buffers will result in an inward movement sliding rack, and means for moving said j rack including a revoluble shaft, and a sega sliding rack, and means for moving said rack including a revoluble shaft, a segmental pinion carried by the shaft and engag ing said rack, ratchet teeth formed on said rack and a pawl adapted to engage the ratchet teeth, as the rack is moved inward.

I 3. In a car coupling, the combination with ahook, of a screw coupling pivotally connected to the hook, a guide member having a curved under face secured to the screw coupling, a rack slidably mounted adjacent said hook, an upturned end on said rack, bar carried bythe rack and engaging beneath the guide'member to "raise the coupling as the rack is moved forward, a shaft extending transversely above the rack, a V

segmental pinion-fixed on the shaft and meshing with the rack, a bar slidably mounted rearwardly of the hook and movable by the hook, a drum on said shaft and a chain wound around said drum and con nected to the bar last mentioned, whereby rearward movement of the bar rotates said shaft.

In testimony whereof, we affix our signatures, in presence of two witnesses.
